Hello everyone, Kithrixx here. I was lucky enough to have this video loaded before it went down. As a result, I got my grubby little hands on the skill descriptions for all skills in Krieg's skill trees. Ain't I a stinker? Unfortunately because the dude in the video didn't actually level anything, I'm not wholly sure what does and doesn't have multiple ranks, so you'll have to use logic to figure that one out by yourselves.

[SIZE=large]TIER 3[/SIZE]Blood Bath - Kill Skill
Killing an enemy with a grenade or explosion increases Weapon Damage for each stack of Bloodlust. An enemy killed this way has a greater chance to drop grenade ammo.

Next Level:
Weapon Damage/Stack: +0.5%
Grenade Drop Chance: 15%

Buzz Axe Bombardier
When thrown, your buzz axe now has Dynamite attached to it which explodes on impact.

Next level: Axe go BOOM!

Fuel the Blood – Kill Skill

Blood Trance

[SIZE=large]TIER 6[/SIZE]Bloodsplosion
Killing an enemy causes them to explode with an Elemental Nova matching the element of the damage that killed it (Non-elemental damage will cause an explosive nova). Nova damage is increased for each stack of Bloodlust.

Any Overkill Damage is also added to damage caused by an Elemental Nova.

[SIZE=large]TIER 3[/SIZE]Thrill of the Kill
A percentage of Overkill Damage (damage that is over and above what was needed to kill the enemy) is returned to you as Health. The lower your health the higher the percentage.

Next Level:
Returns up to 50% of Overkill damage done as Health.

Light the Fuse
Fight For Your Life is replaced with Light the Fuse. During Light the Fuse you pull out a live bundle o dynamite and can move normally. The bundle detonates when the timer runs out. If you kill someone you are revived.

Getting a revive with the bundle explosion gives you bonus Movement Speed for the remainder of the time that was left in Light the Fuse.

Throw Dynamite sticks with Fire. Detonate bundle by holding Action.

Next Level:
Bundle Kill Movement Speed: +40%

[SIZE=large]TIER 4[/SIZE]Salt the Wound
Taking damage from an enemy while your shield is down adds a stack of Salt the Wound.

Redeem the Soul
You can instantly Revive down teammates. After reviving a teammate in this way you must Fight For Your Life. You may revive in this way only once each time Buzz axe Rampage is on cooldown.

[SIZE=large]TIER 6[/SIZE]Release the Beast
Activating the Buzz Axe Rampage when at or below 33% of your max health remaining instantly refills your health and transforms you into a Badass Psycho Mutant. You deal increased Melee Damage and receive significant damage reduction for the duration of the rampage.

When you return to normal, your Buzz Axe Rampage is instantly recharged.
(There is an ! next to the health bar when below 33%.)
